GRI'POR CLUTCH To BE Usso ON ENDLESS-CABLE WAYS.

, SPECIFICATION forming part of Letters Patent No. 289,527, datedDecember 4, 1883.

) Application filed septemberl, 1883. (No model.)

To aZZ whom, it may concern:

Be it known that we, WILLIAM A. GILDAY and THoMAsM. HEoKMAN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gri s or Clutches to be nsed on Endless-Gable l ays, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to grips or clutches to be used on endless-cable ways; and the improvements consist in the mannerof constructing said grip and the means whereby it is operated, aswill be hereinafter described, and more particularly pointed out. in the claims.

In the accompanyingdrawings, Figure 1 represents a side elevation of a car having our improvements attached thereto. Fig. 2 Fig. 3 is an end elevation. Fig. 4 is a side view of the gripping device and connecting mechanism. Fig. 5 is a part cross-section and part end view of the grip and connections. Fig; 6 is one of the bars that support the grip and (See Fig. 4.) Fig. 7 shows the grip in position on the cable when passing around a curve in the track. Fig. 8 shows a section of the tube containing the cable with the grip raised, so as to allow it to pass over another cable, represented by the dotted lines and running at right angles to the first one. l

A A is the frame-work supporting the grip and its connections. This frame is held in position by bearings on the axle at either side of the car. l i

B B are guides, upon which the whole gripping device is moved or worked up and down. 0 is a cross-head, which slides upon the guides B B.

D D are two bars fastened at their upper ends to the cross-head O, and joined at their lower ends to the gripping device proper.

E is a central pressure-bar operating the grip. The faces of the bars D D and pressurebar E are all provided with cogs, those on the pressure-bar E extending some distanceabove and beyond the cogs on the bars D D,as shown in Fig. 4E.

i L L are the two parts of the grip.

a a are two bars or levers connecting the grip to the pressure-bar E.

M is a bolt connecting the two parts of the grip and securing them to the supportingbars D D.

I) is a bolt passing through the slot 0, and

joining the bars a a to the pressure-bar E.

side of the grip, to facilitate the passage of the grip around a curve, as shown in Fig. 7. y

F is the tube inclosing the cable; G, the cable; 9, a second cable running at right angles to the first.

On the bottom of the tube F are placed a sufficient number of the rollers h to properly support and carry the cable G.

m m are spiral springs supporting the bearings of the rollers h. By the use of these spiral springs the rollers h are held in the proper position to supportthe cable, and at the same time theprogress of the grip is not interfered with, as the springs will allow the bearings to be forced down by the grip when passing over. R is avertical shaft extending upward from the under side of the bottom of the car. The upper end of this shaft is provided with the hand-wheel 1. To the lower end is secured the beveled cog-wheel 8.

His a shaft extending under the bottom of the car, as shown in Figs. 1 and 2.

nis a beveled cog-wheel on one end of the shaft H, and gearing into the wheels.

h is a cog-wheel 011 the other end of the shaft H. This cog-wheel gears into the cogs on the face of the pressure-bar E and bars D D.

The grip being in the position shown in Fig. 8, the method of operating is as follows, viz: The hand-wheel r on the shaft B being turned in the required directiom'moves the beveled-cog-wheel s, which operates the beveled-gear wheel a, thus conveying the motion to the horizontal shaft H, and revolving the wheel h, which in turn operates on the cogs on the pressure-bar E and bars D D, lowering them until the gripping device is brought in contact with the cable. Then, as the cogwheel h has passed over all of the cogs on the bars D D,a continued movement will force the pressure-bars E still farther and cause the grip L L to tightly grasp the cable, as shown in Figs. 4 and 5. The slot 0 in the pressurebar E allows of a lateral movement, and prevents a strain when passing around curves, and the increased number of cogs on the said pressure-bar gives it an independent movement only sufiicient to open and close the grip. To raise the grip so that it can pass over another cable, or to-take it out entirely, (the proper openings in the tube being provided,) it-is only necessary to continue turning the hand-wheel 4*.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. In a clutch for endless-cable ways, the combination of the jaws L L, pivoted together at a point between the lower and upper ends, with the levers a a, pivoted to the jaws above the point where they are joined together, the pressure bar E, and suitable means for operating the same, whereby the spreading of the top of the jaws causes them to pinch at their lower ends, as set forth.

2. In a clutch for endless-cable ways, the

jaws L L, bars D D, and pressure-bar E, in combination with the wheel h, simultaneously operating the bars D D and E, substantially as shown and described.

3. The j aws L L, connected with the pressurebar E, in combination with the bars D D, guides B B, and cross-head O, substantially as described.

4. In a cable-grip, the combination of the centrally-pivoted jaws L L, levers a a,operated to spread the tops of the jaws, and thereby cause them to pinch at the bottom, means for operating the jaws, the cable G, and rollers d d, in the base of jaws, for contact with the cable, as set forth.

5. In a cable-grip, the combination, with the pivoted jaws and means for operating them, of the rollers 01 d, for contact with the cable, and rollers ff, on the exterior thereof, for contact with the sides of the tunnel, as set forth.

6. The tube F and rollers h, having the bearings supported by the springs m m, in combination with the gripping device of an endless-cable way, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
